Average = sum(X)/n = 60/3 = 20
The average is 22.
18.
To find the average you need to add the two numbers together and divide by two. 18 + 22 = 40 40 / 2 = 20 The answer is 20.
It is 20, the middle number when they are arranged in order.
The average of 18 and 22 is 18+22/2 = 20
Average = sum(X)/n = 60/3 = 20
The average is 22.
19.75 is the average.
14+16+16+18+22= 4(16)+22= 64+22= 86 86/5= 17.2 17.2
18.
To find the average you need to add the two numbers together and divide by two. 18 + 22 = 40 40 / 2 = 20 The answer is 20.
16 18 22 28 The median (middle number when numbers are in numerical order) is 20.
It is 20, the middle number when they are arranged in order.
16, 18, 20, 22, 24 and 26.
In the example provided, the quartiles are: 25% = 16.5 (the median of {15, 16, 17, 18}) 50% = 18.5 (the median of {15, 16, 17, 18, 19, 20, 21, 22}) 75% = 20.5 (the median of (19, 20, 21, 22})
12, 14, 15, 16, 18, 20, 21, 22
